It can be efficient with Cylinder deactivation but also if fossil fuels were cheaper. What if we reversed the cost of electricity vs fossil fuels? Would we be saying gas powered cars are more efficient. It seems like neither are good for the environment when we include manufacturing, use, storage and disposal.

Thanks for another awesome video man! I've watched many other videos on the GT4 RS and nobody described the engine/gearing feel clearly like you did. I want the DeMan version SO bad 😁
You gotta give it to Porsche. Easily the most aggressive factory launch control out there. And it works great. And you can use it back to back to back to back and it couldn't care less lol.

Right? Yea hey guess what song I'm singing: dee do dee dee dee dee dee, dee do dee dee do dee dee dee dee do, dee dee do, dee dee do, do dee do. duh do dee do.
You put too much hope in engine layout. It is not better, just different. Slightly less traction and slightly more snappy at oversteer because of smaller polar moment of inertia but better balance. It is a tradeoff. Cayman is better because it is smaller. 911 got too big for normal roads.
@@jonboy602 Which one is faster on track, 911 gt3 rs or Cayman gt4 rs? Also, those are still not race cars. Design of race cars is even more dominated by downforce and technical rules and this usually means some advantage for mid engined cars, in a big part due to aerodynamics (more place for rear diffuser).
Length difference between gt4rs and 992 gt3 is less than 12cm, so they are almost equal in size. Advantage gt3 has are suspension and rear wheel steering. Also the engine which wasn't designed for midengine layout. Really great car, with superior engine layout, almost has it all. But still slower than GT3 because of mentioned reasons.
Handling isn't determined by layout alone. Cayman would never be faster than gt3, porsche screwed it up on purpose on the development stage. Most important part of this is crappy mcpherson suspension front AND back. You can't possibly fix that.

That's a very ironic statement, considering they've been doing just that, since the early 2000s. Almost all of their GT RS cars set record around the ring, when they were launched. Some were even created expressly for that purpose, like the 997 GT2 RS, which was designed to beat the GT-R lap time.

Greaser, you don’t know what you are talking about. In the ‘70s Porsche sent out a notice to its dealers to be nice to Datsun Z owners because many only owned a Z because it was all they could afford at that time but what they wanted was a 911.
I love how you can hear the roar of the the intake, it's not coming through the car speakers, and I'll bet it is pretty quiet outside of the car. Porsche for the win! Thank you for sharing Jason!
They finally gave their car that has the engine where it belongs enough power! We all knew they were holding the Cayman back all those years. I owned a 987.2 and the handling was amazing.
I do think the Cayman was supposed to be a less powerful version of the 911, kinda of an entry level to the performance cars. Giving 400+ HP to a newbie is dangerous
Anyone remember Clarkson's brilliant review of the "Coxster" (Cayman) from way back? He lamented the fact that the Cayman wasn't as good as it could be, and put up a chart, showing how it's power was neatly snuggled in between the Boxster & 911. 😃

I love swan neck wing mounts! I did a final project on them for a fluid class. RC scale model simulation and 3d printed model for wind tunnel testing to validate the simulation.
As a suggestion, please consider doing a video on the difference between the EA9A1 And the EA9A2Evo engine. As we know, the EA9A2Evo engine used in the GT4 is a bespoke engine with the same bore to stoke ratio as the EA9A1 engine. I’m very Curious in why the EA9A1 engine seems to be a more superior engine? Great video btw. Best channel ever
I just got a 997.2 earlier this week. Crazy how I'm seeing all these Porsche videos pop up all of a sudden. I love it already. Wish I could afford this one!!
@@JuanPabloRiojasGaming no, I'm not talking about this particular gt4rs. I'm talking about Porsche videos in general. Haven't even looked up Porsche videos on RUclips under this account, so I don't know why it's been recommended all of a sudden.
When I want to see solid reviews of an exciting high performance car, all I need is, 1 from you and 1 with Chris Harris at the wheel and on the mic. Chris’ for the amusing hyperbole, wit and awesome driving footage; yours for the no-nonsense, perspectives that we Engineers all appreciate.
I was most interested in those goose-necked spoiler supports. Your mention of Laminar flow led me into deep thoughts on spoilers surfaces and tripped turbulent airflow. Perhaps it would be better to have airfoils stick straight out from the sides of the bumper. Cars would be hella wide, and more dangerous than ever, but think of that unobstructed airflow. Thank you for the video!
the sides of the car probably generate more turnbulence than the top, with wheel arches, wheels, etc you wouldn't get the same surface anyway as a rear spoiler. plus increasing frontal area. as long as its high enough, rear spoiler seems just better. at least for the rear downforce
Or just have the supports at the ends of the wing, all the way out to the fenders! Think Plymouth Roadrunner. Then stack them 6 tall like Wingo from the Pixar movie Cars.
What a beautiful car. I like when he actually lets it run through the gears and shift. That's the fastest shifts I have ever heard. Blip.... Blip.. it's in the next gear before it's left the last is sounds like.
When are you doing an in depth feature on this engine mate? I clicked on this because that’s what I was hoping to see….your usual excellent discussion of design elements…
Glad to hear the km/h references in the end it makes things so much easier, American engineering analyst here by the way. It is amazing VW finally green lighted a car like this, so much more fun/cost ratio than almost anything out there, with all the factory C8s, Zupras, Camaros and Mustangs I see at trackdays recently I am sure they are trying to cash in on the cheaper fun car segment.
I’m one of the biggest EV supporters (Fan boy if you wish), have been my entire life. Yet I can/do still appreciate an awesome machine like this! The performance and sound ROCK! Not sure why most feel they need to be either EV or ICE… Thanks for the vid Jason!
Different ways to look at this video. To me the main takeaway was ”why do we even bother with combistion engines anymore?” I mean yes this Porsche is truly impressive and amazing, but it takes this pinnacle of engineering to be ”almost in ev territory” in responsiveness. And we’re talking 50-100k EV vs 150k petrol car.
While I find the hypocrisy of the "lightweight" fabric door polls next to the power window controls a great example of marketing trumping engineering at Porsche, I have to say this is the ultimate Porsche for me. Just wish it wasn't so pricy :-/
porsche knows exactly what strings they can tug on and still not piss anyone off. either way i work on these for a living and that window regulator in the regular gt4 is all of 3.5 lbs. id say power windows adds 15lbs across the platform. big whoop.
That's the most consistent request/"complaint" is that shorter gearing would be more fun but it seems to be otherwise a pinnacle of fantastic engineering. Can't wait to get mine!
Jason, maybe sometime you can do a compare/contrast video on the various types of transmission and the terminology employed - manual, automatic, semi-automatic, sequential, H-shift, torque converter, no torque converter, torque converter that can be shifted manually, no torque converter that can shift automatically, two-pedal, three pedal, two-pedal manual, etc. - explaining advantages and disadvantages of each in various contexts. Or maybe videos. EDIT: Forgot to mention that the motivation for this off topic comment was the fact that I had to go look up PDK transmission. I drive a car with a torque converter automatic that lets me shift manually if I want to. I like this because I’m not wearing out my old left knee constantly pumping a clutch pedal in traffic. But unlike the “real” manuals I grew up with, this transmission babysits me by downshifting automatically so that I don’t lug down or stall the engine when I’m slowing down (but will let me rev as high as I want without automatically upshifting). Are there torque converter automatics that don’t do this? Also, are there two-pedal “real” manuals - i.e., the driver does not have to manually engage the clutch when starting moving from a stop?
On your edit, VAG's DSG (direct shift gearbox) is an automatic gearbox without a torque converter, dual clutches which are computer controlled, two pedal driving - they have 'manual' mode which also doesn't shift unless you're at the top or bottom of the safe RPM range. In terms of the babysitting, what would you prefer the vehicle do instead of downshifting? the alternatives are to use more engine power (in a range still safe) or stall out - both of these options aren't really safe or comfortable. In first gear, the transmission losses in fluid coupled automatics allow the wheels to be stationary while the engine still rotates, at the 'cost' of heating the working fluid
@@stefanvanzyl9090 Thanks for the reply. Back in the day I stalled my 3-pedal manuals a few times not getting the clutch fully disengaged in time. Came with the territory and didn’t seem to be that much of a safety issue. But I understand the point on a torque converter xmission. So when Jason and others say they are so happy that manufacturer A has put a “manual transmission” in their model B car because they personally prefer manual xmissions - a comment you hear very often - are they talking about (1) no torque converter, (2) 3 pedals even if one “pedal” is a paddle on the steering wheel to operate the clutch, (3) either sequential or H-pattern, (4) either single clutch assembly or dual/multi clutch (5) lever or paddle shifters on the steering wheel or both; OR does it have to be (1) no torque converter, (2) 3 ACTUAL pedals, (3) H-pattern only, (4) single clutch assembly, (5) lever only?
@@robertbutsch1802 I can't speak for Jason (or any other reviewer) - I just know that driving a fluid coupled automatic isn't fun at all for me. It feels slow, disconnected and unresponsive. I personally drive a Jetta with a DSG, and have plenty of experience with manuals, CVTs, fluid coupled autos, DSG and a dual clutch manual C4 ZR1 - i absolutely prefer the DSG as first place, and the ZR1's dual clutch as second place. The draw of a manual transmission is mostly related to being the polar opposite of the "generic" automatic transmission feeling, and secondly believing to be in "full control" of the vehicle. I put it in inverted commas because cars these days prompt us when to shift anyway, meaning that the car's computer still gets what *it* wants, we oblige - New VW manuals are also able to restart the engine automatically if it stalled, just after you press the clutch - sort of like an extension stop-start feature. other vehicles may also offer this, I don't know. Single clutch manuals are slower to shift and less fuel efficient than DSG in almost all circumstances where the weight and size difference would be inconsequential
It's interesting that they can get away with MacPherson struts in such a sporty car. Obviously it doesn't have much suspension travel meaning the geometry doesn't change very much.
@Karlavilizar Smithjonesmartinez yeah I meant to say it’s crazy that the Miata and Audis come with double in front and multi link in the rear standard thank you
As far as your content, I really missed the EE part, this felt more like a top gear review. Would love to know a bit more about the clever engineering parts
Love Porsche and really enjoy your videos on them and all things engineering! A great library of information and good content. If I have one complaint it is this: If you are going to state facts and figures such as the weight/mass of a vehicle etc, then please pop up some text with the metric equivalent of lbs alongside your regular graphics! You've done it before so I'm not bothered that much in this video as I am unlikely to ever own an GT4 RS. The rest of the world has no idea what you are talking about when quoting lbs, so kilogrammes or even in grams of you prefer would be much appreciated! Keep up the great education! Sow those engineering seeds! Love it
I think you meant that it was noticeably different from the GT3 since you're actually driving the GT4. But we know what you meant. Great video and beautiful car I didn't even know they existed till I watched this
Hi Jason, just wondering, could you explain why some cars have 1" bigger wheels at the back? Like, why, when it's the front wheels that need more brake clearance? Thanks
From Lamborghini: *_"Having a larger diameter rear wheel increases the amount of rubber that contacts the road along the axis of the vehicle which increases your acceleration potential. When you accelerate, much of your vehicle’s weight shifts to the rear. By comparison, the front wheels don’t need as large a contact patch to take care of steering and braking."_*
Interesting analysis on the carbon wheels, cool to know the thought process on those. So why did they include carbon ceramic brakes when Porsche has explicitly said that steel brakes are better for track cars?
I wouldn't say steel brakes are "better" for track cars, they're just significantly cheaper. Sized appropriately, they can handle the heat. The big advantage of carbon rotors is the weight. Takes out a huge amount of unsprung, rotating mass. That's great for so many performance reasons. Full details here: ruclips.net/video/VBd9y3mxzCM/видео.html
"Carbon" wheels, as far as I know, are CFRP (carbon fiber reinforced polymer). So they're just strong plastic, which can't take much heat. Carbon brake rotors are pure carbon, no plastic. Which takes lots of heat.
@@EngineeringExplained totally understand the weight aspect, I only find it interesting that Porsche specifically says they recommend heavy track users to go with steel brakes but put carbon brakes on this track day special. And then also have a reason for not going with carbon wheels based on track use.
@@soaringvulture carbon ceramic is what the rotors are made of. It's carbon fiber, binders, silicon, etcs. So not technically pure carbon but primarily carbon yes.
@@dbeckMSP brakes and wheels are not the same. Any curb or damage to the wheels can result in catastrophic failure. Brakes are much more resilient and protected
I am pretty sure the immediate response is more of a question of calibration than of the individual throttle bodies. On the old Audi S4 4.2 NA engine you could literally feel how the throttle opened very slowly to avoid jerks in the driveline. Horrible!
In the case of the car he owns (Model 3 Performance (4200lbs)). So about 33% more weight, and that's comparing it to a high end sports car. If you take the last sedan I had (Kia Stinger GT), which is a better comparison, you're at almost the same weight (4000lbs). Same 0-60 time for the Tesla and the Porsche (3.2 seconds). Waaaaay more practical with no transmission and very little maintenance. Of course the Porsche will be quicker around a track, but the Model 3 does pretty well for $85k less which means normal people can actually buy one. The only thing electrics need to catch up on is range. The Tesla is at best around 200 miles at highway speeds.
The DAF Daffodil used a CVT and could go as fast in reverse as it did go forwards. That opened up the possibility for an entirely new class of motor sports - Daffodil racing in reverse.
Responsiveness is one of the top things I search for in a car! As Jason says if you ask for %60 it gives that response, so this must be a fantastic car to own! I really love to own such cars, not today’s boring crossovers and trucks!
That they did what everyone wanted since the Cayman R, is amazing. One of very few manufacturers listening to their customers despite modern regulations and fun brakes applied in favour for "better economy and planet saving". Like if individual traffic would change anything major...
Hi Jason. Great video report. Thoughts on your comments and the questions you raised. 1. Having more aggressive gearing on all Cayman models. I suspect that this has more to do with brand-wide emission regulations than anything else. The fewer "dirtier" cars they sell (e.g. with close gear ratios) the fewer electric powered vehicles they have to sell to offset it. 2. As you would know, the stiffer the springs, the less problematic the compromises (e.g. toe-in & camber change) inherent in MacPherson struts become. 3. Moving the engine from rear to mid. Of course, In the old days we'd just invert the transmission and modify the casing as required 🙂
Jason, one thing that Porsche is NOTORIOUS for doing is downrating the engine power on the Cayman and Boxster cars. They do this electronically. For example, my own car, a '14 Cayman S has it's M1.23 engine rated at 325 hp. The same engine is used in the base 911 and it produces 352 hp. How can this be? Because on my car as the engine approaches redline, the throttle plate is electronically closed to limit the power to "only" 325! This has been proven many times and I have actually seen this happen on my iCarSoft PORII OBDII interface. This device specifically shows throttle position and you can watch it close partially near redline. If there is any difference at all in the exhaust then it is only a few horsepower, not 9. Great video as always!
No matter what people say. Porsche are 100% the best performance car maker alive... Their engineering is insane - don't think Lamborghini nor Ferrari would be able to nail the rear engine car like Porsche has *i know this is mid-engined* Props to Porsche!!
gt4rs is a huge slice of yes please. Excellent work on those cad models for flipping the engine :). Are we going to get an update on the supercharged ND1?

I love how you can hear the roar of the the intake, it's not coming through the car speakers, and I'll bet it is pretty quiet outside of the car. Porsche for the win! Thank you for sharing Jason!
I'd be surprised if this car has speakers at all. The motor would drown them out and you're supposed to be driving, not listening to classic rock.
This is why I love Porsche. They go above and beyond! And they’re just perfect!!
They finally gave their car that has the engine where it belongs enough power! We all knew they were holding the Cayman back all those years. I owned a 987.2 and the handling was amazing.
I do think the Cayman was supposed to be a less powerful version of the 911, kinda of an entry level to the performance cars. Giving 400+ HP to a newbie is dangerous
@@alpenfoxvideo7255 nobody is buying a GT4 RS or even a GT4 as their first car lol.
Anyone remember Clarkson's brilliant review of the "Coxster" (Cayman) from way back? He lamented the fact that the Cayman wasn't as good as it could be, and put up a chart, showing how it's power was neatly snuggled in between the Boxster & 911. 😃
I’m glad you did this video while driving. It’s more entertaining seeing you drive around a track while *explaining the science* .
*That GT4 RS sounds amazing* 🤯
was just thinking the same thing!!!!
Oh My God, that sound. The GT3RS was already on the top for my dream list I think the GT4RS just knocked it to 2nd...
Yeah
sameee
I loved Porsche also
Angels start singing at 8500 RPM.
@@smithiness ain't that the truth, 9k rpm 6 banger n/a God what an engine. Only thing that ive heard in terms of cars that can beat that is probably that lfa v10 purr and my personal favourite rotaries. 😍 don't get me wrong supercharger whines are up there but man high reving engines are just engineering masterpiece and musically orgasmic for lack of a better word
Porsche has been putting out some amazing cars to round out the end of internal combustion.
Look around you ice isn’t dead
I'm so glad you got to do a video on this engine again!
It's just so good!
Best looking CAR ever build. That's what I dreamt of 30-40 years ago, playing with our matchbox toy cars on the floor.
Such freat presentation! No uhs or ums, technical while driving too. 10/10
I love swan neck wing mounts!
I did a final project on them for a fluid class. RC scale model simulation and 3d printed model for wind tunnel testing to validate the simulation.
oh we need a video on that. seriously.
As a suggestion, please consider doing a video on the difference between the EA9A1 And the EA9A2Evo engine. As we know, the EA9A2Evo engine used in the GT4 is a bespoke engine with the same bore to stoke ratio as the EA9A1 engine. I’m very Curious in why the EA9A1 engine seems to be a more superior engine?
Great video btw. Best channel ever
I just got a 997.2 earlier this week. Crazy how I'm seeing all these Porsche videos pop up all of a sudden. I love it already. Wish I could afford this one!!
You’re seeing them because the car just got released.
I would want this and a toyota gr supra
@@JuanPabloRiojasGaming no, I'm not talking about this particular gt4rs. I'm talking about Porsche videos in general. Haven't even looked up Porsche videos on RUclips under this account, so I don't know why it's been recommended all of a sudden.
congrats on the 7.2, last of the analogue rides. if u ever wondered if u were being watched, Porsche is watching you now, haa. enjoy!
@@davidalexandreg oh yeah! Even if I crave more horsepower in the future, not getting rid of it.
When I want to see solid reviews of an exciting high performance car, all I need is, 1 from you and 1 with Chris Harris at the wheel and on the mic. Chris’ for the amusing hyperbole, wit and awesome driving footage; yours for the no-nonsense, perspectives that we Engineers all appreciate.
I was most interested in those goose-necked spoiler supports. Your mention of Laminar flow led me into deep thoughts on spoilers surfaces and tripped turbulent airflow. Perhaps it would be better to have airfoils stick straight out from the sides of the bumper. Cars would be hella wide, and more dangerous than ever, but think of that unobstructed airflow. Thank you for the video!
the sides of the car probably generate more turnbulence than the top, with wheel arches, wheels, etc
you wouldn't get the same surface anyway as a rear spoiler. plus increasing frontal area. as long as its high enough, rear spoiler seems just better. at least for the rear downforce
Or just have the supports at the ends of the wing, all the way out to the fenders! Think Plymouth Roadrunner. Then stack them 6 tall like Wingo from the Pixar movie Cars.
@@DurfDiggler - Yes - that's the answer. Look at modern F1 cars. And the Ferrari F40
@@DurfDiggler yes, as the end supports can act as fences. 👍
What a beautiful car. I like when he actually lets it run through the gears and shift. That's the fastest shifts I have ever heard. Blip.... Blip.. it's in the next gear before it's left the last is sounds like.
It's a dual clutch transmission. It *is* in the next gear before it has left the last one!
When are you doing an in depth feature on this engine mate? I clicked on this because that’s what I was hoping to see….your usual excellent discussion of design elements…
Man.... that glorious sound of the flat six!
What a great way to kick off a video! That engine sounds amazing when launched
Glad to hear the km/h references in the end it makes things so much easier, American engineering analyst here by the way. It is amazing VW finally green lighted a car like this, so much more fun/cost ratio than almost anything out there, with all the factory C8s, Zupras, Camaros and Mustangs I see at trackdays recently I am sure they are trying to cash in on the cheaper fun car segment.
Not sure how cheap these are. Saw one recently for 911Turbo S money from ten years ago. All of those other vehicles will be significantly less.
Beautiful video, Jason. Love that you filmed this at Willow Springs.
Amazing car! Those Michelin Cup 2Rs are legit. Picking up 5-6 seconds just because of tires is insane.
Such a good review
Thanks, Eric!
The 4th video that I see on that car, this one is the only one witch not only got me actual info but answered all my question.
Thumbs up
I’m one of the biggest EV supporters (Fan boy if you wish), have been my entire life. Yet I can/do still appreciate an awesome machine like this! The performance and sound ROCK!
Not sure why most feel they need to be either EV or ICE…
Thanks for the vid Jason!
The new EV racecar concept by Porsche is built on the Cayman platform...and the next gen Cayman/Boxster is going to be electric...
Different ways to look at this video. To me the main takeaway was ”why do we even bother with combistion engines anymore?”
I mean yes this Porsche is truly impressive and amazing, but it takes this pinnacle of engineering to be ”almost in ev territory” in responsiveness. And we’re talking 50-100k EV vs 150k petrol car.
Evs are gay
Congratulations. I'm so glad this channel is growing so well, great to see a channel get the recognition they deserve.
Beautiful car! That sound is delicious 🤩
I gotta drive a Porsche. I did get to drive a 914-6 very breifly, over 40 years ago. It was incredible, especially the brakes.
Mid engine is definitely the correct location
I've been dreaming of this car ever since the 4.0 engine was made.
Intoxicating sound at 9,000 rpm. Addictive, pure adrenaline, only suitable for circuits and experienced people at the controls.
While I find the hypocrisy of the "lightweight" fabric door polls next to the power window controls a great example of marketing trumping engineering at Porsche, I have to say this is the ultimate Porsche for me. Just wish it wasn't so pricy :-/
porsche knows exactly what strings they can tug on and still not piss anyone off. either way i work on these for a living and that window regulator in the regular gt4 is all of 3.5 lbs. id say power windows adds 15lbs across the platform. big whoop.
That's the most consistent request/"complaint" is that shorter gearing would be more fun but it seems to be otherwise a pinnacle of fantastic engineering. Can't wait to get mine!
Jason, maybe sometime you can do a compare/contrast video on the various types of transmission and the terminology employed - manual, automatic, semi-automatic, sequential, H-shift, torque converter, no torque converter, torque converter that can be shifted manually, no torque converter that can shift automatically, two-pedal, three pedal, two-pedal manual, etc. - explaining advantages and disadvantages of each in various contexts. Or maybe videos.
EDIT: Forgot to mention that the motivation for this off topic comment was the fact that I had to go look up PDK transmission. I drive a car with a torque converter automatic that lets me shift manually if I want to. I like this because I’m not wearing out my old left knee constantly pumping a clutch pedal in traffic. But unlike the “real” manuals I grew up with, this transmission babysits me by downshifting automatically so that I don’t lug down or stall the engine when I’m slowing down (but will let me rev as high as I want without automatically upshifting). Are there torque converter automatics that don’t do this? Also, are there two-pedal “real” manuals - i.e., the driver does not have to manually engage the clutch when starting moving from a stop?
I have videos on most of these subjects. :) ruclips.net/p/PL7B5B6479699EB204
On your edit, VAG's DSG (direct shift gearbox) is an automatic gearbox without a torque converter, dual clutches which are computer controlled, two pedal driving - they have 'manual' mode which also doesn't shift unless you're at the top or bottom of the safe RPM range.
In terms of the babysitting, what would you prefer the vehicle do instead of downshifting? the alternatives are to use more engine power (in a range still safe) or stall out - both of these options aren't really safe or comfortable. In first gear, the transmission losses in fluid coupled automatics allow the wheels to be stationary while the engine still rotates, at the 'cost' of heating the working fluid
@@stefanvanzyl9090 Thanks for the reply. Back in the day I stalled my 3-pedal manuals a few times not getting the clutch fully disengaged in time. Came with the territory and didn’t seem to be that much of a safety issue. But I understand the point on a torque converter xmission. So when Jason and others say they are so happy that manufacturer A has put a “manual transmission” in their model B car because they personally prefer manual xmissions - a comment you hear very often - are they talking about (1) no torque converter, (2) 3 pedals even if one “pedal” is a paddle on the steering wheel to operate the clutch, (3) either sequential or H-pattern, (4) either single clutch assembly or dual/multi clutch (5) lever or paddle shifters on the steering wheel or both; OR does it have to be (1) no torque converter, (2) 3 ACTUAL pedals, (3) H-pattern only, (4) single clutch assembly, (5) lever only?
@@EngineeringExplained Jason, may I request you help check out the Punch powertrain dt1 transmission.
@@robertbutsch1802 I can't speak for Jason (or any other reviewer) - I just know that driving a fluid coupled automatic isn't fun at all for me. It feels slow, disconnected and unresponsive. I personally drive a Jetta with a DSG, and have plenty of experience with manuals, CVTs, fluid coupled autos, DSG and a dual clutch manual C4 ZR1 - i absolutely prefer the DSG as first place, and the ZR1's dual clutch as second place.
The draw of a manual transmission is mostly related to being the polar opposite of the "generic" automatic transmission feeling, and secondly believing to be in "full control" of the vehicle.
I put it in inverted commas because cars these days prompt us when to shift anyway, meaning that the car's computer still gets what *it* wants, we oblige - New VW manuals are also able to restart the engine automatically if it stalled, just after you press the clutch - sort of like an extension stop-start feature. other vehicles may also offer this, I don't know.
Single clutch manuals are slower to shift and less fuel efficient than DSG in almost all circumstances where the weight and size difference would be inconsequential
The colors of the cars are amazing. Especially that blue.
It's interesting that they can get away with MacPherson struts in such a sporty car. Obviously it doesn't have much suspension travel meaning the geometry doesn't change very much.
My thoughts exactly but it’s crazy that the Miata and most Audis come standard with it. And some acuras.
@Karlavilizar Smithjonesmartinez yeah I meant to say it’s crazy that the Miata and Audis come with double in front and multi link in the rear standard thank you
Definitely the best driver's sports car made in a very long time. Looking forward to owning one of these one day.
I've owned a Model S P100D for a couple years but this is fuc*ing better!!
As far as your content, I really missed the EE part, this felt more like a top gear review. Would love to know a bit more about the clever engineering parts
I was expecting some April fools video today like "how you can recharge a Tesla battery with your urine"
Underrated comment
Damn, you mean you can’t?
So I’ve been pissing on Teslas for a couple of years to no effect. Damn, damn, damn.
Great review of an incredible car! That beast gives me the shivers! I can only imagine what it was like feeding her the beans.
I don’t care how efficient this is vs an ev, that sound and I can fix it in my own garage which are things they want to go away.
Definitely my dream car!! I'm on my second Porsche. I'd LOVE to make this one my third!
Love Porsche and really enjoy your videos on them and all things engineering! A great library of information and good content.
If I have one complaint it is this: If you are going to state facts and figures such as the weight/mass of a vehicle etc, then please pop up some text with the metric equivalent of lbs alongside your regular graphics! You've done it before so I'm not bothered that much in this video as I am unlikely to ever own an GT4 RS.
The rest of the world has no idea what you are talking about when quoting lbs, so kilogrammes or even in grams of you prefer would be much appreciated!
Keep up the great education! Sow those engineering seeds! Love it
That is a video with wonderful visuals, but all I heard was: 'Excitement, excitement, excitement'. Please have a version with commentary, thank you 😋
Man it's my dream to drive a Porsche on a track it would be amazing
best review so far
Perfect N/A car, with an Engineered titanium exaust. hmm maybe beyond perfection.
Thanks for doing the hard work of evaluating the GT4RS.
"A perfect engine is something that every internal combustion engine maker should strive for, regardless of gold and silver."

Very cool. The wing helps make the Cayman look better because I think the back end looks a little bare otherwise.
Can we get uncut footage of you doing the push laps in it?
Shoot, not a bad idea; should have uploaded them to my second channel. Thanks for the idea!
@@EngineeringExplained you got a second channel?? Must subscribe!
Yeah, I’d be into that, if there’s anything notable I wouldn’t mind a little voiceover.
I think you meant that it was noticeably different from the GT3 since you're actually driving the GT4. But we know what you meant. Great video and beautiful car I didn't even know they existed till I watched this
Hi Jason, just wondering, could you explain why some cars have 1" bigger wheels at the back? Like, why, when it's the front wheels that need more brake clearance? Thanks
@@nidhishshivashankar4885 But then why do drag cars use like 15” wheels? It’s because more sidewall = better straight-line grip
From Lamborghini:
*_"Having a larger diameter rear wheel increases the amount of rubber that contacts the road along the axis of the vehicle which increases your acceleration potential. When you accelerate, much of your vehicle’s weight shifts to the rear. By comparison, the front wheels don’t need as large a contact patch to take care of steering and braking."_*
that engine sound is mesmerizing
Interesting analysis on the carbon wheels, cool to know the thought process on those. So why did they include carbon ceramic brakes when Porsche has explicitly said that steel brakes are better for track cars?
I wouldn't say steel brakes are "better" for track cars, they're just significantly cheaper. Sized appropriately, they can handle the heat. The big advantage of carbon rotors is the weight. Takes out a huge amount of unsprung, rotating mass. That's great for so many performance reasons. Full details here: ruclips.net/video/VBd9y3mxzCM/видео.html
"Carbon" wheels, as far as I know, are CFRP (carbon fiber reinforced polymer). So they're just strong plastic, which can't take much heat. Carbon brake rotors are pure carbon, no plastic. Which takes lots of heat.
@@EngineeringExplained totally understand the weight aspect, I only find it interesting that Porsche specifically says they recommend heavy track users to go with steel brakes but put carbon brakes on this track day special. And then also have a reason for not going with carbon wheels based on track use.
@@soaringvulture carbon ceramic is what the rotors are made of. It's carbon fiber, binders, silicon, etcs. So not technically pure carbon but primarily carbon yes.
@@dbeckMSP brakes and wheels are not the same. Any curb or damage to the wheels can result in catastrophic failure. Brakes are much more resilient and protected
Man that scream.. gives me goosebumps 🤤
I am pretty sure the immediate response is more of a question of calibration than of the individual throttle bodies. On the old Audi S4 4.2 NA engine you could literally feel how the throttle opened very slowly to avoid jerks in the driveline. Horrible!
Loved the description and visuals on the power difference between this and the gt3
Electric motors are 2-3x more efficient than ICE --- but have to move a car that weighs 50% more due to battery weight
There, I fixed it for you.
In the case of the car he owns (Model 3 Performance (4200lbs)). So about 33% more weight, and that's comparing it to a high end sports car. If you take the last sedan I had (Kia Stinger GT), which is a better comparison, you're at almost the same weight (4000lbs). Same 0-60 time for the Tesla and the Porsche (3.2 seconds). Waaaaay more practical with no transmission and very little maintenance. Of course the Porsche will be quicker around a track, but the Model 3 does pretty well for $85k less which means normal people can actually buy one. The only thing electrics need to catch up on is range. The Tesla is at best around 200 miles at highway speeds.
As a Cayman owner I must say, I love this video.
They should of kept the 7 reverse gears
The DAF Daffodil used a CVT and could go as fast in reverse as it did go forwards. That opened up the possibility for an entirely new class of motor sports - Daffodil racing in reverse.
Amazing video Jason. Great car
This would be the perfect car with a manual gearbox and a manual handbrake
I have NO idea why they are pushing electronic handbrake. It's not reliable.
@@AutumnWind92 even if it IS reliable, it’s no fun.
That GT4 in Electric Blue looks stunning. Not a “shouty” car at all and beautifully stylish.
officially called Gentian Blue
This is the car you would keep for life. Especially since internal combustion engines are going extinct very soon.
Aaaw, don't hold your breath!
Finally a 911 engine in the cayman. A proper mid-engine sports car. Kudos to Porsche. 👍
it's sad that naturally aspirated engines have become so rare. i enjoy a 100ps na engine more than a 190ps turbo engine
No just no. The only time na is better for me is in a much larger capacity engine such as a 3.5l V6 and bigger .
beautiful car with a strong engine!
I’ll still take the slower model to get a real manual gearbox.
One of my dream cars! I was driving a 987 Cayman, always wish can have a ultimate Cayman, here it is!
Of course 991 GT2RS and GT3RS on the list, haha!
That clock ticks in a really satisfying way. Can't really explain why.
Porsche is making some sick cars , they keep dreams alive .
Responsiveness is one of the top things I search for in a car! As Jason says if you ask for %60 it gives that response, so this must be a fantastic car to own! I really love to own such cars, not today’s boring crossovers and trucks!
I'm gonna go pick one up tomorrow, now. You talked me into it.
Lol, you wish. The waiting list is months
My pick for best drivers cars 2022 This porsche, Nissan Z, GR 86. They clearly had that vision in mind to keep it simple and purely about the drive.
Car goes vroom 🤤. ICE until I die.
I’m speechless as a Cayman S 981 owner…wow ..love it
Forget all other supercars and hypercars.. GT4 RS is just 🤤🤤🤤
That they did what everyone wanted since the Cayman R, is amazing. One of very few manufacturers listening to their customers despite modern regulations and fun brakes applied in favour for "better economy and planet saving". Like if individual traffic would change anything major...
Hi Jason. Great video report. Thoughts on your comments and the questions you raised.
1. Having more aggressive gearing on all Cayman models. I suspect that this has more to do with brand-wide emission regulations than anything else. The fewer "dirtier" cars they sell (e.g. with close gear ratios) the fewer electric powered vehicles they have to sell to offset it.
2. As you would know, the stiffer the springs, the less problematic the compromises (e.g. toe-in & camber change) inherent in MacPherson struts become.
3. Moving the engine from rear to mid. Of course, In the old days we'd just invert the transmission and modify the casing as required 🙂
Best-sounding 6-cylinder in history, one of the best-sounding cars ever made.
Jason, one thing that Porsche is NOTORIOUS for doing is downrating the engine power on the Cayman and Boxster cars. They do this electronically. For example, my own car, a '14 Cayman S has it's M1.23 engine rated at 325 hp. The same engine is used in the base 911 and it produces 352 hp. How can this be? Because on my car as the engine approaches redline, the throttle plate is electronically closed to limit the power to "only" 325! This has been proven many times and I have actually seen this happen on my iCarSoft PORII OBDII interface. This device specifically shows throttle position and you can watch it close partially near redline.
If there is any difference at all in the exhaust then it is only a few horsepower, not 9.
Great video as always!
I mean, 9 out of 500 is not much of a difference, I certainly don’t know enough about exhaust to say if they’re lying but it seems feasible.
No matter what people say. Porsche are 100% the best performance car maker alive... Their engineering is insane - don't think Lamborghini nor Ferrari would be able to nail the rear engine car like Porsche has *i know this is mid-engined*
Props to Porsche!!
The GT4RS is my dream car, i'd love to drive one from coast to coast. It's also the only car i'd be thrilled with in bright yellow..lol
Top notch analysis.
gt4rs is a huge slice of yes please. Excellent work on those cad models for flipping the engine :). Are we going to get an update on the supercharged ND1?
Porsche is one of the few automakers to keep the sports car combustion spirit safe and sound. 😌
They keep showing that gorgeous blue GT4 when talking comparisons and all I can think is that I’d much rather have that clean look and 6MT over the RS.
This was very good Jason...
That engine sound alone is worth every dollar. It does something to me..........
